Anchored Polysiloxane-Modified Polyurethane Coatings and Uses thereof
This patented technology introduces a next-generation polyurethane coating enhanced with anchored polysiloxane segments. Unlike conventional fouling-release or protective coatings where silicone migrates or leaches over time, this formulation chemically anchors the polysiloxane within the polymer network, ensuring long-term durability, hydrophobicity,...

Non-Isocyanate Polyurethane Low Surface Energy Coatings (GC)
Glycidyl carbamate (GC) functional resins are used due to their high mechanical strength, toughness and abrasion and chemical resistance associated with polyurethanes as well as the convenience of epoxy-amine chemistry. Webster et al have combined these resins with polydimethylsiloxane to develop self-stratified coatings that yield coatings having low...

A Novel Amphiphilic Siloxane-Polyurethane Fouling-Release Coating
This technology describes a curable polyurethane coating that integrates both hydrophobic and hydrophilic components, polydimethylsiloxane (PDMS) and poly(ethylene glycol) methyl ether (mPEG), to create an amphiphilic surface that resists biofouling. When cured, the coating self-stratifies, forming a surface layer that minimizes adhesion of marine organisms...
